Not sure if it's been tried. It wouldn't get very far anyway. Ramadan is about 7 weeks before Christmas and all the administrators who control the NYC school system and set the rules are Jewish. The judges here are extremely liberal on culture related issues. The whole thing is an anti-Christian culture war. The thing is minorities are not the ones complaining. Hispanics are almost entirely Catholics, the Chinese rarely complain about things like this and black people are mostly Christian. None of these groups has a problem with Christian symbols.

The only ones who have a problem are the left and the Muslims.
